 Any hints on what might have changed from 11-RELEASE to 11.1-RELEASE and 
 11.1-STABLE?

Confirmed, thank you :)

Going back to RELENG-11.1 solved it, so the slip must be quite recent.

The system works unstable

2017-09-14 Thread wishmaster
Hi!

My 11.0-STABLE system had been working stable for a three last years, but 
became unstable a week ago. The system just freezes about once/2 days (at 
night) and no responsive via network, nothing in the console.
Before the first freezing I had made updates of applications in the base system 
and jails.
Options VIMAGE and Linux compat. are enabled.

The first thought was bad sectors on the HDD, but  dd if=/dev/ada0 of=/dev/null 
bs=128k rejected this one.

How can I debug this situation?

Thank,
Vit

If you have remote console via IPMI it might be an idea to leave an 
active top session so you can see the last point at which the machine 
stopped. It may provided a pointer to bad process e.g. eating all the 
machine RAM.

Still working on it.  We are trying to replicate the FreeBSD 11.1
running in a Hyper-V VM setup in our test lab.  We have ping/snmp/netflow
network simulators that can create large amounts of real network traffic to
see if it reliably triggers the problem.
